Hi Leone,
let's see if we can verify / ascertain more information:
- You are using the same ROS2 distribution version and package updates on both machines, and it works on one of them and fails on the other?
- Could you provide a bit more context about the error? Does the nerian_stereo node just terminate after showing just that message without any other text?
- Are you using ros2 param or the launch configuration in any way during launch to change the default parameters (other than the IP etc.), or does the node crash when started on its own without any parameter changes? What other ROS2 nodes, if any, are running when you start the node?
- It would be helpful if you could share the device configuration, so we can verify that there are no oddities or bugs in the settings. (Web interface, "Maintenance -> Download Configuration"). You can of course PM the resulting tgz archive if you do not wish to attach it here.
I will try to reproduce the problem, and also make the parameter code more robust and look at adding more runtime logging capabilities for the ROS2 parameter setup process.
We will get to the bottom of this.
